The Valley Company, a subsidiary of Walter Kidde & Co., Inc. of Bay City, Michigan, is documented as the manufacturer of the distinctive 1978 Spectra IV cocktail pinball table, a notable entry in vintage pinball history that reflects late-1970s solid-state arcade design and playfield experimentation; the Spectra IV is a four-player cocktail-format, solid-state machine with an alphanumeric display and archived ROMs and manuals useful for restoration and collectors. The game’s standout feature is its manually rotating playfield—allowing multiplayer play without moving positions—paired with two flippers, three pop bumpers, a rollunder spinner, a captive ball, kick-out holes and a left kickback lane, making Spectra IV one of the few rotating-playfield solid-state machines and a sought-after example of a playfield-gimmick cocktail pinball for collectors and historians.
